Design and application of visual security system solutions for stadiums
1. Program background
Recently, with the wonderful conclusion of the Chengdu Universiade and the upcoming opening of the Hangzhou Asian Games, large-scale sports events have brought people spiritual and cultural enjoyment on the one hand , and on the other hand, due to the large number of spectators and sudden on-site Due to factors such as the changing situation and high density of information , there are many on-site incidents in the stadium . Therefore, the construction of a visual security system has become the top priority in the construction of the stadium's digital system.
2. Construction goals and requirements
1. Focus on prevention and handling of emergencies, realize emergency linkage and assist analysis and decision-making, and promptly warn and control the occurrence of various suspicious phenomena and emergencies in the stadium.
2. Video surveillance of sports venues needs to cover the entire venue and the surrounding areas of the venue, and the coverage of monitoring points is large. Sports venues are densely populated. When an incident occurs, it is necessary to clearly and quickly see the activities and changes of personnel . Video surveillance needs to have a lot of capabilities. High real-time performance and clarity.
3. The system can detect abnormal events at the first time and solve them promptly and effectively to ensure that the system can operate stably, reliably and continuously.
3. System design
1. Overall concept
A sports venue is generally a building complex composed of multiple functional area buildings. It is not only necessary to consider the safety protection needs of the main stadium itself, but also to build a comprehensive, safe and effective technical protection system based on the overall sports building complex. Specifically, it includes video surveillance systems , intelligent analysis early warning systems , perimeter and anti-theft alarm systems, fire protection systems, etc.
2. S keyeVSS national standard video fusion cloud platform
Today we mainly explain how to use the S keyeVSS national standard video fusion cloud platform to organically combine these subsystems from information collection, data transmission, storage, and system control output to achieve platform-level interconnection and alarm linkage to meet the needs of sports The need for unified control and comprehensive management of the venue's visual security system .
3. Introduction to SkeyeVSS platform
SkeyeVSS is a video convergence + AI intelligent analysis gateway platform based on end-edge-cloud integrated architecture developed by Shikai Technology. The SkeyeVSS platform supports video aggregation and convergence management, is compatible with multiple types of equipment and multi-protocol access, and can provide Its video functions include: video surveillance, plug-in-free live recording, cloud storage, retrieval and playback, intelligent alarms, platform cascading, etc. SkeyeVSS has powerful video integration capabilities and AI cloud-edge scheduling capabilities, and can realize computing power allocation, resource scheduling, computing and storage, intelligent processing, agile deployment and other services based on end, edge, and cloud architecture.
4. Implementation method
- Front-end deployment: Use high-definition video surveillance equipment in important parts of the stadium . Digital non-compressed high-definition dome cameras can be deployed in large-scale and key monitoring parts such as stadium entrances and exits, around the square, outdoor parking lots, auditorium areas, and panoramic views of the stadium; audience Network high-definition cameras can be deployed in key locations such as entrances and exits, rostrum (area), VIP rooms (area), VIP channels, referee areas, athletes areas, competition management areas, and news media areas. For other general halls or passages where the monitoring target range is small and the prevention requirements are not high, standard-definition or high-definition cameras can be flexibly deployed.
- Platform management: The platform uses H.264/H.265 video compression technology to transmit 720P/1080P/4K high-definition video in 4G/5G/WIFI/broadband and other network environments. The video screen supports 1, 4, 9, and 16 minutes. Screen playback and scheduled tour playback support arbitrary switching of channel videos to enable centralized viewing of multi- scene images in stadiums .
- Video output: Based on advanced streaming media transcoding and processing technology, the platform can externally distribute RTSP, RTMP, FLV, HLS, WebRTC and other video streams, covering all terminals and all platforms, including PCs, mobile phones, tablets, WeChat, and e-commerce platforms. Screen/TV wall, WEB H5, etc. Staff can view real-time video images of the stadium through the Internet anytime and anywhere .
4. System functions and applications
1. Emergency linkage and intelligent early warning
Intelligent monitoring and early warning are implemented in sensitive areas and targets to handle emergencies promptly and accurately. Through video analysis technology, users can preset different alarm rules in different camera scenes based on the video content analysis function. Once the target violates the predefined rules in the scene, the system will automatically issue an alarm, thereby providing emergency services . Disposal provides the most intuitive video information.
2. Platform interconnection and video resource sharing
The platform can be deployed in a distributed manner, and can realize cascading between platforms through the GB28181 standard protocol, allowing multi-system docking to provide video image resource sharing, meeting the concurrent access requirements of a large number of users, and providing stable real-time video preview, history Services such as image downloading and authorized access control can effectively solve resource sharing problems . When a sports venue is hosting an event, security personnel inside the venue, public security, armed police, firefighting and other government departments can use the platform to understand and grasp the situation inside and around the venue in real time .
3. Rapid integration and development
The platform can provide a unified service HTTP Restful API interface to the outside world to connect devices, connect data, and connect applications, facilitate the rapid integration of third-party platforms, and have functions such as permission management, device management, streaming media forwarding and storage management, and realize access control and alarm Alarm linkage and emergency plans for , fire protection and other systems, and authorized open interfaces for public security and other government departments or units to realize the sharing of video resources .
